To all whom it may concern:

Be it known that I, FRANK M. ILER, of Rico,

l in the county of Dolores and State of Colorado,

have invented certain new and useful Improvements in Pumping Apparatus;and I do hereby declare the following to be a fu1l,'clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same.

My invention relates to improvements in mining-pumps, or mine-sinkingpumps, the primary object being to construct pumping apparatus of theCharacter indicated, whereby there is no condensation of steam betweenthe surface and bottom of the mine as with the steam-pumps heretoforeused; wherein the buckets are actuated by ropes or' cables extendingupthrough the shaft of the mine; that occupies less space than asteam-pump having the same capacity; whose wearing parts a're morequickly renewablej from which obstructions, that interfere with theoperation of the pump, can be more readily removed and wherein'the meansof attachment of the suction-hose is greatly simplified.

VVith this object in view, and to the end of realizing certain otheradvantages hereinafter detailed, my invention consists in certainfeatures of construction, and in combinations of parts hereinafterdescribed and poihted out in the claims.

In the accompanying drawings, Figure l is an elevation, mostly incentral Vertical section, showing the barrels of the pump, heads of thesame, dac. Fig. 2 is a central Vertical section showing, among otherthings, the lower portion of the delivery-pipe, the connection betweenthe bucket-stems or rods and operating-cables, and the means employedwhereby when one bucket is elevated or hoisted, the other bucketispositively lowered: Fig. 3 is a Vertical section on line 3-3, Fig. l.Fig. 4 is a transverse section on line 4-4, Fig. 2, looking downwardly.Fig. 5 is a transverse section on line 5-5, Fig. 1, looking downwardly.Fig. 6 is an elevation showing the Operating crankgshaft and thelever-mechanism, &c., operatively connecting the bucketactuating cableswith said shaft. Fig. 7 is an enlarged'detail in -perspectivehereinafter described. Fig.'S is an enlarged elevation, partly insection, of one of the buckets. Fig. 9 is a detail in perspectivehereiuafter described. Fig. 10 is a plan in detail, partly in section',and Figs. 11 and 12 are details in perspective, all hereinaft-erdescribed.

Referring to the drawings, A A represent the upright barrels of thepump, and B and C the upper and lower chambered heads of the barrels,respectively, the barrels having heads in common as shown in Fig. 1. Thelower head O is in open relation with the suetion-hose D suitablyconnected with said head as hereinafter described. The upper head Bcommunicates with delivery-pipe E (see Fig. 2) that is suitablyconnected with said head, preferably as hereinafter described, andextends to the surface above.V

Gdesignates the suction-valves of the pump; H the buckets, and I thebucket or deliveryvalves.

H' represents the bucket-stems or rods that extend upwardly throughstuffrng-boxes J suitably attached to the upper head of thepump-barrels, and the bucket-rods or stems, at their upper ends, areconnected, respectively, preferably by means of turn-buckles, H2, withropes or cables, 1-13. that in turn are suitably connected (see Fig. 6)with bellcrank-levers, 1-14, fulcrumed, as at H5, to any 'suitablesupport on the surface above and operatively` connected with each otherby means of a link or connecting-rod, H6, that in turn is operativelyconnected in any suitable manner with the' Operating machinery, forinstance, as shown, with the crank, 1-17, of a crank-shaft, HB, to whichpower is applied in any manner. The two bell-cranks H4 are so arrangedrelative to each other that the two buckets of the pump aresimultaneouslyactuated in opposite direetions, respectively. The meansthus employed by me for hoisting and lowering the buckets is muchsimpler and cheaper and does not possess less efticiency than any meansor mechanism heretofore employed for the purpose. Suitable means areprovided whereby upon hoisting either one of the buckets the otherbucket is positively lowered. Preferable means for the purpose isillustrated IOO member 1-19 of the one bncket-rod or stem, to which itis suitably attached, downwardly to and over a sheave or pulley K'suitably supported by the upper head of the pump-barrel, and thenceretnrns and is suitably secured to the projecting-member 1-19 of theother bucket-stem or rod. By this construction, it will be observed thatas either one of the buckets is elevated, the other bucket owing to thedownward pull exerted by rope or cable K, upon its rod or stem, ispositively lowered, said rope or cable, of course having lengthsntficient to accommodate the stroke of bucket-rods or stems.

The delivery-pipe E is connected with the upper head of the pump-barrelin any suitable manner. Head B is enlarged upwardly at its centralportion, as at B', and the Chamber of said enlarged portion of the head,through which chamber passes the water or liquid pumped, is divided, atits central portion to accommodate the location of sheave K'. Portion B'of head B, at its upper end, is providedwith an external fiange B2, thatis bolted to external fiange L' of the casing of a chamber L into whichthe lower section, e, of the delivery pipe extends. M designates a ringor collar that rests upon and is bolted, as at M', to the upper end ofcasing of chamber L, ring or collar M, at the top, being provided withan internal fiange, m, that is adapted to engage the top side of anexternal flange n of a ring N that is screw-threaded internally andmounted upon the correspondingly externally screw-threaded lower end ofpipesection e', that constitutes the delivery-pipesection next abovesection e.

I would here remark that the delivery-pipe is usually composed offlanged sections of pipe, with the flanges at adjacent or contiguousends of the pipe-Sections bolted together, and that the last sectionthat is secured in place is section e'. Sometimes, however, upon thecompletion of the delivery-pipe,excepting the connection of said sectione' with the pipe-section next above, it is found that the bolt-holes inthe flange at the upper end of section e' do not register with thebolt-holes in the flange at the lower end of the pipe-section nextabove. Hence the importance of being able to turn pipe-section e' inorder to bring the holes in the flange at the npperend of saidpipe-section into registering relation with the holes in the flange atthe lower end of the pipe-section next above. This is convenientlyaccomplished by the construction hereinbefore described, it being merelynecessary to loosen bolts M' that secure ring or collar M, wherenponpipe-section e' can be readily turned in the one direction or the other,to bring the same into the position required relative to thepipe-section next above.

The bucket-stemsor rods H' operate in suitable guide-ways O' formed bythe opposing snrfaces of a pair of lngsO projectinglaterally from theadjacent side of the easing of cham tease? ber L, as shown very clearlyin Figs. 4 and 9, and are held in the respective guide-ways, by means ofa cap-plate O2, removably secured to the outer ends of lugs O in thefollowing mannerz-The Cap-plate at or near each end is secured to theadjacent lug by means of an eye-bolt, O3. Both bolts O3 are pivotedwithin slots O4 of the respective lugs O (see Fig. O) and have nuts O5mounted upon the screwthreaded shanks thereof at the outer side of thecap'plate. The cap-plate is slotted, as at O6, to enable the one bolt tobe swung, upon loosening the nut thereon, out of engagement with thecap-plate as shown in dotted lines, Fig. 4, whereupon the other boltwith the capplate can be swung away from the respective bncket-rod orstem, as shown in dotted lines, same figure, to enable the removal ofsaid rod or stem from the respective guide-ways. Each pair of lugs islocated a suitable distance apart to accommodate between them thelocation and operation of rope or cable K.

The pump is supported in any suitable manner, preferably from timber, Q,in the mine-shaft. (See Fig. 3.) Preferable means for snpporting thepump from said timber is illustrated in Figs. 3 and 4, wherein thecenter portion B' of head B, at one side and at a suitable intervalapart is provided with two laterally-projecting flanges or lugs B3 that,at their outer end, have secured thcreto a yoke R that connects and hasbolted thereto two upright bars S. Each bat` S is embraced or engaged bya pair of clamping-jaws S' caused to tightly engage and clamp therespective bar by means of a bolt S? that extends through the pair ofclamping-jaws, and the one clamping-jaw is provided with a tooth orspnr, S3, that engages the snpporting-timber. Supporting-timber Q maynot be found at the same elevation in all mine-shafts. Henceelamping-jaws Sfare adjustable up and down said bars S, and the latterare quite long.

A feature of my invention of vast importance consists in the simple andconvenient means employed for supporting the suetionhose or pipe fromthe lower head of the pump, and referring to Figs. 1, 3 and 5 that showthe means referred to, the snction-hose-nipple cl is screwed into asleeve, T, that, at its upper end engages a gasket, U, seated in anundercnt groove or recess C',in the lower end of head C. Sleeve T, inits lower end, is provided with an annular groove or recess, T', that iseugaged by the lower hooks V' of hook-ended upright-bars, V, that extendnpwardly into holes or eavities C2, in laterally-projecting lugs C3 ofhead C, and terminate at their npper ends, in hooks, V2, that areengaged by wedges, VV, driven in undersaidhooks through lateralperforations O4 in lugs C3, the wedges at or near their rednced endsbeing provided, respectively, with a laterally-projecting lug or memberXV' that serves as a stop to prevent the wedges from hacking outentirely in tease? loosening the .same -bywhich construction there is"no liabi'lity of the wedges becoming lost.

Joints X connect the barrels of the"pump With the respective heads ofthe pump. A gasket or packing X' is interposed between eachjoint X andthe ends of the pump-barrels, said packing or gaskets being seated inunderout annular grooves, X2, of the joints. A gasket or packing, X3, isinterposed between each joint X and heads B and Cof the pump, packing orgaskets XS engaging undercut grooves X4 in said pump-heads. Suction-Valves G of the pump are preferably located within the lower joints X,being suitably seated preferably in the lower portion of said joints.

Heads B and C, pump-barrels and connecting-joints are held assembled bymeans of two bolts or rods, Y, located on opposite sides of the pump,respectively, and pivotally secured at their upper ends, as atlY', tolaterally-projecting lugs or ears. Y4, of the upper head B. Said boltsor rods extend downwardly, respectively, through a slot inlaterally-projecting lugs C5 of the lower head, said connecting-bolts orrods being secured in place by means of nuts Y2 mounted thereon belowlugs C5 and preferably further secured by means of pins or cutters, Y,extending laterally through said lugs at the outer side of the rods orbolts. The pump-barrels are suitably hinged upon said rods orbolts Y insuch a manner that by loosenin g bolts or rods Y, the parts will loosenor separate sufficiently to permit the pumpbarrels to be swung laterallyupon said bolts or rods for repairs, cleaning or other purposes. Apreferable hinge-connection of the lpump-barrels with aforesaid rods orbolts is shown in Fig. 1, wherein the barrels are provided,respectively, with a laterally projecting lug or ear a that preferablypartially embraces 'the respective bolt or rod and rests upon a collar,a',,loosely mounted upon the bolt or rod, but held in place by means ofa collar, ai, rigidly mounted upon therod or bolt preferably by means ofa set-screw or bolt as, the hole a4 of lug or ear a engaging the uprightpintle 0.5 of collar a'.

The pump-barrels have preferably an ear a at or near either end torender the barrels reversible so that in the assemblage of parts noparticular care need be exercised as to which end'of the pump-barrelwill come upper or lowermost. Screws or bolts a3 are of course .loosenedpreparatory to the afore-mentioned swinging aside of the pump-barrels.If desired, the headsof the pump may be tied to.- gether, centrallybetween the pump-barrels, by means of a tie-rod, T'r, but said rodshould be made of two parts joined together by means of a turn-buckle orcoupling as shown.

To prevent the upper joints X from dropping upon swinging thepump-barrels laterally, as hereinbefore indicated, said joints areprovided, respectively, (see Fig. 3) with laterally-projecting 'lugs X5provided with openended Vertical slots Xfor the passage of eyebolts X7,the eyes whereof are uppermost and engage the eyes of eye-bolts, X9,that are suitably secured to laterally-projecting lugs or ears b of headB. Upon loosening nuts X8 that are normally tightened against lugs X5,eye-bolts X7can'be swun g outwardl y, as shown in dotted lines, Fig. 3,to permit the removal of upper joints X as required in replaoing 01'renewing the packing at the ends of the joints or for other purposes.

An important feature concerning upper joints X consists in the downwardtaper of the internal wall of said joints, the latter, at the lower end,corresponding in diameter with the diameter of the pu mp-barrel, buthaving their diameter gradually increasing toward their upper end tofacilitate the entrance of the buckets into the pump-barrels upon theassemblage of parts, more especially where elastic packing is used onthe buckets.

The delivery-valves I are seated upon the buckets in the usual manner.

Another important feature of my invention consists in suitable means forexpanding the packing of the buckets without necessitating the removalof the buckets from the pumpbarrel. Preferable means for the purpose isshown in Fig. 1, wherein one of the buckets is shown in section andwhereinV I' designates the annular packing of the bucket, and in Figs. 7and 8 wherein 12 designates an elastic split ring that engages the innerside of the packing. The edges of said ring, at the split in the ringare preferably V-shaped, (see Fig. 7) and engage corresponding groovesin the edges of a wedge, 13, that at its reduced end terminates in ascrew-threaded shank 14 that has mounted thereon a nut, 15, engaging thelower end of the bucket. The bucket comprises, preferably, two spidersor perforated conical members 16, between the rims of which the packingis oonfined, the hubs of said spiders orconical members abutting eachother and nicely mounted upon the lower end of the plunger-rod or stem,a butt-ring 17, preferably of steel, being interposed between a shoulderh on the bucket-rod or stem and the upper lmember 16 and engaging arecess in the hub of said member 16, the plunger-rod or stem beingscrew-threaded at its lower end and extending below the bucket where ithas mounted thereon anut, h', that, in conjunction with shoulder h onthe bucket-stem or rod, securely holds the parts of the bucket together.The upper end of wedge 13 is adapted to extend above split ring 12 andthe rim of the upper spider or conical member of the bucket isrecessed,as at 18, Fig. 8, to accommodate the location of said end ofthe wedge. The shank of the wedge extends through a hole l9 in the rimof the lower spider or conical member of the bucket and the wedge isoperated by means of nut h' that, as already indicated, is mounted onthe shank of the wedge below the bucket.

.By turning said nut in the one direction or the other the 'packing ofthe bucket is ex- IOC IIO

panded or coutracted as desired. Hence, it will be observed that whenthe packing becomes worn, it need not be renewed immediately, but issimply readjnsted by expanding the same and thereby maintaining therequired engagement or fit of the packing with the internal wall of therespective barrel of the pump.

Nut h' is preferablyof the split variety, as shown more clearly in Fig.10, and clamped upon the bucket-stem or rod by means of a bolt and nut,712, by loosening which the splitnut can be quickly removed whenrequired.

Referring again to t-he means employed for actnating the buckets, IWould remark that the Operating ropes or cables are not shown attacheddirectly to the links that depend from the bell-cranks, but (see Fig.11)extend through half-clamp-boxes, Z, (one of which is shown detached inFig. 12) that tightly clamp the ropes or cable between them, theinternal surface of the half clamp-boxes being corrugated, grooved orotherwise formed, as at Z' Fig. 12, to conform to the extenal surface ofthe rope. The Operating cables should be of such length that they canreadily be lengthened when required by separating or loosening theclamp-boxes and leaving out more rope or cable. The companionhalf-clamp-boxes are preferably clainped upon the respective rope orcable by means of bolts Z2 that extend through corresponding holes inthe clampboxes and are suspended from the respective bell-cranklever H4above by'means of links Z3.
